DNS Record Types Explained
Address record that maps a domain name to an IPv4 address. This is the most fundamental type of DNS record and is used to connect a domain to a web server.
Example: example.com. 3600 IN A 192.0.2.1
Similar to an A record, but maps a domain name to an IPv6 address instead of IPv4. Used for domains that support IPv6 connectivity.
Example: example.com. 3600 IN AAAA 2001:db8::1
Mail Exchange record that specifies the mail servers responsible for receiving email for the domain. Includes a priority value to determine mail server order.
Example: example.com. 3600 IN MX 10 mail.example.com.
Name Server record that delegates a DNS zone to a server authoritative for that zone. Specifies which servers contain the actual DNS records for a domain.
Example: example.com. 3600 IN NS ns1.example.com.
Text record that contains arbitrary text data. Often used for SPF, DKIM, domain verification, and other services that need to confirm domain ownership.
Example: example.com. 3600 IN TXT "v=spf1 ip4:192.0.2.0/24 -all"
Canonical Name record that maps one domain or subdomain to another domain name. Used for creating domain aliases.
Example: www.example.com. 3600 IN CNAME example.com.
Start of Authority record that contains administrative information about the DNS zone, including serial number, refresh intervals, and responsible contact.
Example: example.com. 3600 IN SOA ns1.example.com. admin.example.com. 2023050101 7200 3600 1209600 86400
Certificate Authority Authorization record that specifies which certificate authorities are allowed to issue certificates for the domain.
Example: example.com. 3600 IN CAA 0 issue "letsencrypt.org"
